1. 650 series overview
The 650 series IEDs provide both customized and
configured solutions. With the customized IEDs
you have the freedom to completely adapt the
functionality according to your needs.
The 650 series IEDs provide optimum 'off-the-
shelf', ready-to-use solutions. It is configured with
complete protection functionality and default
parameters to meet the needs of a wide range of
applications for generation, transmission and sub-
transmission grids.
The 650 series IEDs include:
• Customized versions providing the possibility to
adapt the functionality to the application needs.
• Configured solutions are completely ready to
use solutions optimized for a wide range of
applications for generation, transmission and
sub-transmission grids.
• Support for user-defined names in the local
language for signal and function engineering.
• Minimized parameter settings based on default
values and ABB's new global base value
concept. You only need to set those
parameters specific to your own application,
such as the line data.
• GOOSE messaging for horizontal
communication.
• Extended HMI functionality with 15 dynamic
three-color-indication LEDs per page, on up to
three pages, and configurable push-button
shortcuts for different actions.
• Programmable LED text-based labels.
• Settable 1A/5A -rated current inputs.
2. Application
Breaker protection REQ650 IED provides a
standalone solution for applications, where the
functions related to the breaker is not preferred or
suitable to be integrated into the main protection
function that is, the line distance protection for a
line. The advanced automatic reclosing,
synchronizing, synchrocheck and energizing
check functions of REQ650 provides an optimized
stand alone product. This IED also enables well-
structured and reliable protection and control
systems especially in systems where complete
bay control functionality including interlocking is
not required.
REQ650 provides backup to the main protection
with redundant protection and control functions.
Three pre-configured packages have been
defined for the following applications:
• A01: Backup protection functions in a single
busbar single breaker bay with three-phase
trip.
• A11: Backup protection functions in a single
busbar single breaker bay with single-phase
trip.
• B11: Backup protection functions in a
double busbar single breaker bay with single-
phase trip.
The backup protection is mainly based on current
and voltage functions. In line protection
applications, autoreclosing with or without
synchrocheck is available.
The REQ650 IED is delivered pre-configured and
ready for use in the power system. Analogue
inputs and binary inputs/outputs circuits are pre-
defined.
The pre-configured IED can be modified and
adapted to suit specific applications with the
graphical configuration tool ACT inside the
PCM600 tool, For example, using the glue logic
and adjusting the parameter settings.
